Abstract: ABSTRACT OF THE DISCLOSURE A  combustion  turbine  is  provided  with  first stage vane structure having an airfoil portion or vane and inner and outer shrouds.  The vane is formed from a spar which is covered by a shell having inner coolant channels which carry coolant for cooling the shell  (vane)  outer surface.  The coolant  is supplied through coolant chan-nels in the spar, and a limited amount of the coolant is discharged to the hot gas path through the vane trailing edge while most of the coolant is directed to  coolant channels within the shrouds for shroud coolant action and ultimate discharge to  the hot  gas path  through  shroud openings.

Abstract: DIGITAL CONTROLLER            Abstract of the Disclosure A digital controller includes a digital feed-back circuit for use in generating a pulse-width modulated control signal.  The signal is derived from binary signals representing a standard pulse-width signal for the rated output of the power supply plus a correction pulse-width signal reflecting the change in the output level of the power supply.  Logic circuits alter the correction pulse-width signals to provide a balancing correction.  Soft start operation of the power supply together with a selection of operating clock frequencies are also provided.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method of oil recovery for use within an underground formation having an ion exchange capacity.  An aqueous micellar fluid bank containing a surfactant is injected into the formation followed by an injection of the bank with a mobility control fluid, such as a polymer-thickened aqueous solution, into the forma-tion.  The mobility control fluid has a lower salt level but a greater divalent cation-to-monovalent cation ratio than the micellar fluid make-up brine, preconditioning brine or original in-place brine in a reservoir in order to reduce the hardness of the formation fluids in situ generated at the trailing edge of the micellar fluid which in turn reduces the surfactant loss from the micellar fluid.

Abstract: Abstract Aluminum is joined to titanium by welding using so much welding energy that the temperature on the titanium side of the alloying melt boundary remains below 2000°C, while titanium and aluminum do, however, melt at the joint interface.            In a weldment thus obtained, the base material alloys and aluminum filler of which contain at maximum 10 % titanium, there is in the vicinity of the interface between titanium and aluminum only a discontinuous .beta.-phase, dispersed in the aluminum matrix.

Abstract: ABSTRACT           A self-checking system for monitoring the flame of a burner is disclosed.  Radiation from the flame impinges upon two photodetectors which produce two separate but comparable signals. These two signals are applied to a comparator which produces a comparison output which is then used to interpret the signal from one of the sensors so that the comparison output is removed.  On removal of the comparison output signal, if the flame is still present, both sensors will once again provide the comparable signals.  Thus the circuit provides a modulated signal representing alternately affirmative comparison and negation of comparison.          Loss of burner flame or failure or malfunction of any of the circuit components will remove the modulated signal resulting in a failsafe alarm being instigated.

Abstract: ABSTRACT OF THE DISCLOSURE         The double pane window is provided with a drying chamber which is filled with desiccant and an antechamber which extends from the drying chamber to communicate with the surrounding environment at the opposite end.  The ante-chamber prevents a direct exit of dry air from the enclosed spaced between the window panes into the surrounding atmosphere during "breathing" of the window as well as drawing in of moist ambient air into the drying chamber.  The antechamber also brings about a considerable increase in the diffusion resistance for the water vapor diffusion into the desiccant or the space between the window panes.
